LOCOMOTIVE ASH-=PAN.

SPECIFICATION forming part of Letters Patent No. 696,486, dated April 1,1902.

Application filed November 7, 1901. Serial No. 81,478. KNO 711M010 ToI/Z/I whom it 777,04 concern.- I

Be it known that I, JOHN PLAYER, of Chicago, in the county of Cook andState of Illinois, have invented a certain new and useful Improvement inLocomotive Ash-Pans, of

which improvement the following is a specificatiou.

My invention while more particularly designed for application inconnection with lo- IO comotive-boilers of the wide or widened fireboxtype is likewise and equally applicable to those having narrow 1ire-boxes; and its ob ject is to provide an ash-pan which shall presentthe characteristic features of a comparatively large receptacle forashes and other residuum from the fire-box and air-admission passages ofample capacity, through which the proper supply of air to the grate maybe eifected with as little tendency as practicable to the maintenance ofcombustion in the residuum contained in the ash-pan.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure l is a side view in elevation of alocomotive ashpan, illustrating an application of my invention, with thefront and back watenlegs of the fire-boX in section; and Fig. 2, a rearview in elevation of the same with the side waterlegs of the fire-box insection.

My invention is herein illustrated as applied in connection with a widefire-box 5, which is located above a pair of trailing wheels 3. Theupper section or body 23 of the ashpan, which is formed of sheet orplate metal and connected to the fire-box in the usual manner,isinwardly and downwardly tapered, so as to clear the wheels 3 and frame 8of the engine and to direct the ashes and other residuum which drop intoit from the superposed grate toward its middle portion. The lowersection of the "ash-pan, which is preferably made of cast metal, is inthe form of one or more hoppers or discharge-chutes 24:, two being shownin this instance, each of which is open at top to the upper section andhas an inclined bottom, in which there is formed a cleaning ordischargeopening preferably extending throughout the full distancebetween the side and the end walls of the hopper and closed by adischarge-door 25, which is fitted to abut against and make a tightjoint with the walls of the hopper around the discharge-opening.

The discharge-doors are in this instance shown as suspended upon thesides of the hoppers in such manner as to be automatically elosed andmaintained in contact with the bottoms thereof by gravity and areprovided with means for man ually opening them for the discharge ofresiduum from the ashpan, as may from time to time be required. Thisconstruction does not, however, consti- Lute any part of my presentinvention and is the subject of a separate application for LettersPatent filed by me of even date herowith, Serial No. bl,477.

The side sheets of the upper section or body 23 of the ash-pan aresecured in any suitable manner, as by bolts or rivets, to the sidebearers or grate-supports 34:, and in this instance said grate-supportsare shown as provided with integral downward extensionplates 35, whichconstitute, operatively, the upper portions of the side walls of theashpan and may, if preferred, be made integral therewith and bedetachably secured to the grate-supports. A separator 36 is interposedbetween and connected at its upper and lower edges to each of theextension-plates 35 and the upper edge of the adjacent side sheet of theash-pan. The separators 36 are provided for the purposes of dividing theupper portions of the sides of the ash-pan into separate but connectedsections, of forming air-admission passages in said upper portions, andof preventing the escape of ashes by deflect- .ing them toward themiddle of the ash-pan.

In the specific embodiment of the invention shown herein the separatorsare in the form of plates which are inclined correspondingly with theextension-plates and side sheets and are bent or curved transverselyinto a plurality of corrugations or alternate elevations anddepressions, which constitute channels or passages for the admission ofair to the lower side of the grate, these channels being down' wardlyand inwardly inclined, and therefore not presenting avenues for theegress of ashes or other residuum which may fall on the separators fromthe grate, such solid matters being deflected by the inclined surfacesof the separators to the connected portions of the side sheets and alongthe same to the middle portion of the ash-pan. The residuum deposited inthe ash-pan rests thereon entirely below the air-passages, and not beingsubjected to the action of the currents of air entering through the sametendency to maintain combustion in said residuum and the resultantdeteriorating action on the ash-pan are fully obviated.

The specific form of the separators employed is not an essential of myinvention and structural variations of the same may be made in thediscretion of the constructor without departure therefrom. The leadingand characteristic features of a separator embodying my invention arethat it shall be located as near as practicable to the top of theash-pan and form a portion of an upper wall thereof, that it shall formor inclose an air-admission passage or passages, and that it shall be ofsuch construction as to prevent the egress of material from the ash-panthrough said passage orpassages. These ruling conditions may be compliedwith under modifications of form and detail which will readily suggestthemselves to those skilled in the art. Thus, for example, in lieu ofbending or corrugating the plate of the separator it may be providedwith one or more inclined slats or wings in the manner of the devicesknown as louvers, which are employed in ventilating apparatus.

I claim as my invention and desire to secure by Letters Patent 1. Inalocomotive ash-pan, the combination of a body which is open at its topand adapted to be connected thereat to a fire-box, a door or slidecontrolling a discharge-opening in the lower portion of the body, and aseparator, forming a portion of the wall of the body adjacent to the topthereof, and provided with one or more air-admission passages havingwalls located in position to prevent the egress of solid matter.

2. In alocomotive ash-pan, the combination of a body which is open atits top and adapted to be connected thereat to a fire-box, a door orslide controlling a discharge-opening in the lower portion of the body,and a separator, forming a portion of the wall of the body adjacent tothe top thereof, and provided with one or more inwardly and downwardlyinclined air-admission passages.

3. In a locomotive ash-pan, the combination of a body which is open atits top and adapted to be connected thereat to a firebox, a door orslide controlling a discharge-opening in the lower portion of the body,and a separator, forming a portion of the Wall of the body adjacentto-its top, said separator being inwardly and downwardly inclined andbent or corrugated transversely to form one or more air-admissionpassages.
